自制jq分页插件

由于第一次写jq插件，中间有借鉴别人的代码。

 (function(){
    var ms = {

        fillHtml: function(obj, option) {
            obj.empty();
            var totalPage = option.pageCount,
                pageHtml = "",
                dotHtml = "<li><a>...</a></li>",
                tempHtml = "";

            if (option.currentPage > 5) {
                tempHtml = "<li><a class=page-num>1</a></li><li><a class=page-num>2</a></li><li><a>...</a></li>";

                for(var i = option.currentPage - 2 ; i <= (option.currentPage + 2 > totalPage ? totalPage : option.currentPage + 2); i++) {
                    var temp = "<li><a class=page-num>" +i+ "</a></li>";
                    if (option.currentPage === i ) {
                        temp = '<li class="current-page"><a href class=page-num>'+ i +'</a></li>';
                    }

                    if (option.currentPage >= totalPage - 2) {
                        dotHtml = "";
                    }
                    pageHtml += temp;
                };

            }else {

                for(var i = 1; i <= ( 6 > totalPage ? totalPage : 6); i++) {
                    var temp = "<li><a class=page-num>" +i+ "</a></li>";
                    if (option.currentPage === i ) {                //添加选中蓝色背景
                        temp = '<li class="current-page"><a  class=page-num>'+ i +'</a></li>';
                    };

                    if (option.currentPage >= totalPage - 2) {
                        dotHtml = "";
                    }
                    pageHtml += temp;
                };
            }
            
            pageHtml = '<ul>'+
                        '<li class="prev-page"><a>上一页</a></li>' + tempHtml +
                        pageHtml + dotHtml +
                        '<li class="next-page"><a>下一页</a></li></ul>';
            
            obj.append(pageHtml);
        },

        bindEvent: function(obj, option) {

            $(obj).on("click",".page-num",function(){
                if ($(this).parent("li") && $(this).parent("li").hasClass('current-page')) {
                    return;
                }
                var current = Number( $(this).text() );                //点击的页数
                ms.fillHtml(obj, {"currentPage": current, "pageCount": option.pageCount});
                option.backFunction();
            });

            $(obj).on("click",".next-page",function(){
                var current = Number( $(".current-page a").text() );                //下一页
                if (current === option.pageCount){
                    return;
                }
                ms.fillHtml(obj, {"currentPage": current + 1, "pageCount": option.pageCount});
                option.backFunction();
            });

            $(obj).on("click",".prev-page",function(){
                var current = Number( $(".current-page a").text() );                //上一页
                if (current === 1){
                    return;
                }
                ms.fillHtml(obj, {"currentPage": current-1, "pageCount": option.pageCount});
                option.backFunction();
            });
        },
        
        init: function(obj, option){

            return (function(){
                ms.fillHtml(obj, option);
                ms.bindEvent(obj, option);
            })();
        }
    };


    $.fn.creatPage = function(option) {

        var initOption = {
                pageCount: 10,
                currentPage: 1,
                backFunction: function(){}
        };
        option.pageCount = Number(option.pageCount);
        option.currentPage = Number(option.currentPage);
        
        var option = $.extend(initOption, option);
        
        ms.init(this, option);
    }
})()

HTML

<div class="mod-page-cont" id="pageCont">
                       
</div>

用法

$("#pageCont").creatPage({
        pageCount: 18,            //总页数
        currentPage: 1,            //当前选中页
        backFunction: function(){    //回调函数
            
        }
    });
